In this paper, it proposed a new environmental information acquisition system based on smart phones (Smartphone / Pocket PC) which combined with Geographic Information System (GIS), Global Positioning System (GPS), wireless communication technology in allusion to the current actual situation of environmental protection information acquisition in city environmental protection department. System architecture and working principle is analyzed, and it designs the main modules of the software and hardware. In addition, transport protocols and application of the implementation method have been discussed. Experiments show that the environmental information acquisition system has high precision, easy to use, information transfer with high efficiency and reliability. Not only have that, the paper also discusses the effective strategies of network transmission of data encryption and the image transmission rate improvement. In brief, it can effectively enhance the work efficiency of the city environmental protection department when they collect relevant information.
